TELEPHONE-PAY-STATION CABINET.

Beit known that I, HERMAN IGNACIO Wmormus, acitizen of Mexico, residing at Leon in the Province of Gto and Republic of'lvlexico, have invented new and useful Improvements in Telephone- Pay Station Cabinets, of which the following is a specification.

' My invention relates to telephone pay stations and more particularly to a device adapted to hold the telephone instrument but permitting access tothe same upon depositing a coin of the necessary denomination'in a slot.

As is well known telephone companies lose thousands of dollars every year, because has deposited the'pr'oper coin.

of the fact that there is no absolute certain way in which the operator at the central oflice can determine whether or not the persongl'ising the instrument at the pay station Itis an object otmy invention to overcome this difiiculty and to provide a device which will prevent access being had to the instrument until the coin has been actually deposited and registered at the central ofiice.

Another object of my invention ,is to providea device of the above nature which shall be absolutely certain in itsoperation, and

whichshallj have means, whereby an indi-; cator in the'central office is caused to showthe exact denomination of the coin which hasbeen dropped in the' slot, in order to gain access to the instrument and which shall also retain such instrument in aslot compartment-,mnt-il a coin of. some denomination has been deposited.

\Vith the foregoing and other objects in 5 view my invent-ion consists in such details 5 40. combination of parts as will be hereinafter of construction and in't-hearrangement and more fully described and specifically pointed out in the appended claims.

- In describing my invent-ion in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a view of my improved device in front elevation. Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. 1 looking in the direction of the arrow. Fig.- 3 is a view similar to Fig. 2, but taken on th li 3- lookingin the direction of the arrow. Fig. 4- is a horizontal sectional view Specification of Letters Patent.

tion. Mounted upon the inner face of the 'door are keepers 6 and '(which have rooves therein. One of these keepers may e used substantial by using two as shown. More than two may be used if conditions warrant. Pivotally mounted upon the partition 3 are In reducing my invention into practice I 1L construct a receptacle 1 of any suitable material. This receptacle is provided witha'f door 2, which opens into the interior there, of, 'which interior is divided by means of a;

partition '3 intov two compartments 4 and 5.1; respectively, the door 2 opening into com-f, :175'

if desired, but the construction is made more latches 8 and 9 which are provided with hooks and adapted to engage in the grooves in the keepers G and 7 respectively. The

short arms of the latches are thickened or reinforced as at 10, as more clearly shownin Fig. 7 which construction is provided in order that the latches may be more delicately balanced so that the short arm'may counter-balance the superior weight of the longer arm. rod 11 connects the arms of the levers 8 and 9 so as to cause them to operate'simultaneousl 7 Extended through an aperture 12 in the partition 3 is an arm 13 which may be formed integrally with'the lever-9'01 may be attached-thereto in any desired manner. A flattened portion or plate 14.is formed uponthe end of the arm 13, and is disposed immediately beneath the mouth of a chute 15 which is supported in apcrpeudicular pcsition within the compartment 5 by means.-

mentioned of brackets 16 or other suitable supporting devices.

Leading into the chute are a pluralit of superposed slides or coin chutes17 whic connect the slots 18 formed in the .casing 1,

.saidslots' being disposed one above the other 'and graduated in size for different sized coins as isclearly shown in Figs. 1 and 8. All of these slots are normally closed by means of a plate 19, which has an aperture .19.- An elongated slot is formed in the casing 1 in order to permit play of the lever 23. Aspring contact 26 is connected to the other end of the lever the under surface of said contact carrying. a layer of insulating material 27. Mounted upon the rear wall of the casin 1 are a plurality of contact points 28 WhlCh are insulated from said wall as shown. Thesecontact points are so disposed as to be engaged by the spring contact 26 when thelat'termoves-upward as it will do when the handle 24 is pulled down- \vardly. It will be seen however that when said lever :arm moves downwardly the insulating material 27.wil1- come into engagement with the contact points 28 thuspre- -ventin the completion of the circuits except when t 9 spring contact arm is moved upwardly. .A spring 29 is connected to the spring contact arm of the lever 23 and t rough the floor of the casing so as to hold said arm normally in its lowest position. It will also be seen that said 5 ring holds the handle 24 normally in its highest position, and therefore also holds the plate 19 in a corresponding position whereby all of the slots 18 are normally closed. It is of course necessary to insulate the spring contact arm of the lever 23 from the handlearm, and.

therefore insulating material posed between said two arms.

Itfis thought that the operation of my de- 30 is intervicejwill be sufiicientlyclear from the foregoin description. Supposing that five cents 1s to e dropped into the slot in order'to gain access to the telephone instrument, it willbe noted that the handle 24 must beipfuiled' downwardly "until-"the five-cent slot wan a covered by the apertu're 20 as shown in Figs 1 and 2. The coin is then deposited in said slot and slides .down the guide way 17 into the chute 15, anddrops upon the plate 14,"

thus causing the latches 8 and 9 to turn upon V their pivots and unlockthe'door 2, said each contact- 28 traveled over,

-latch normally projecte I tion. Itvwill be seen that the handle 24 being in a'lowered position, the upward. move-' latches being delicately balanced as before or this purpose. When the handle 24 is first pulled'down so as to uncover the five-cent slot tli spring contact 26 comes into engagement with the lowest of the contacts 28.

A suitable electric circuit may be arranged wvhereby said contact may cause a current of electricity to indicate upon a suitable indicator at'the central. oilice the denomination of the coin deposited. When a coin of a larger denomination isto be deposited the handle 24: must be pulled lower down thus causing the spring contact to travel over 7 two or more of the contacts 28, with the indicates a diiferentamount deposited for As soon as the door is opened the handle 24 may be released and the s ring 29 will restore the plates to their initial position the insulating material 27 preventing. any further electrical impulses .from being transmitted to the central ofiice.

Any, suitable electric circuit may ,be devised to accomplish the above purpose,'this forming no part of my "invention, butby result that theindicator at the central oifice way of illustration 1 have shown one form in Fig. 9. Here a conductor 31 extends from the s ring contact arm of the lever; 23 to a suita le source of electrical energy as for inst-ance batteries 32.. Thus conductors 33 areconnected to' the contact 28 and'extend therefrom to a suitable indicator of'any de sired construction, which is to be located at thecentral oflice. j

In order that the .door 2 may be held unlo'ckedlafter the operation of the latches 8 and 9 through the mediumof a falling coin some sort of a latch mechanism-1s necessary. For this purpose I show a cable 35 extendin from the lever 23 downwardly through, an

around a pulley 36 to a latch- 37, which latch i is pivota in turn are fastened to the'partition -3 -in y mounted in brackets 38 which the compartment 4. As ring 39 holds said,

ment of the arm 10 of the latc'h9.will cause said arm to-be engaged by. means ofthe shoulderupon the latch 37. Thedoor'rnay therefore be opened. As soon asthe lever .23 c is restored to its normal position by ,means of the spring 29 the cable 35 will cause said latch .to release the mid "fiermittingthe latteras fall into nip" 3' from which itwill engage the kep'ei- LTwh the door is closed.

It v will be seen that I have i yery simple. and effective means for contain: mg a telephone pay station instrument such as will prevent, the instrument from being used before the proper coin is dcpositd; It will also be noted thatthe parts are iew from said part-i;
